I thought I understood how to work with Payment Options...until I realised I didn't!

Let's say I have three items X,Y,Z that cost $1,$2 and $3, respectively.
I understand how to make a dropdown box to allow the customer to select X,Y, or Z and to set up the price for each using the "Price Multiplier" option, but how do I combine quantity and price within a dropdown box? If the want 2 of item X, how does that work?

Easily done (I hope)...check this out ... http://gunsmoke.me/formtest/pricemultiplier

Let me know if you have any other questions.

Thanks, Gunsmoke.
That does indeed work, but then I would need to list over 20 products and I don't want to see all of them, hence the idea to use a dropdown box so the customer can select only the products they want.
Can I use a quantity AND a dropdown box together?

Yes, you can. Let me work on it for a minute. I misunderstood. What you need to do is use a conditional. It will take a little to setup, but more work for you and less for your customer. I'll have something up in a few minutes ...

Okay, see if this is what you wanted. I put in a checklist where you can select the items you want, then input a quantity.
There is also an option to select a single item, using a drop down. The only disadvantage to that is that you can only select a single item, then input the quantity. But if that is what you are looking for. Completely doable
